A Noether-Lefschetz theorem for varieties of r-planes in complete intersections

Zhi Jiang

Let X be a very general complete intersection in complex projective space and we denote by $F_{r} (X)$ the variety of r-planes in X, for $r \geq 1$ . We show that the Picard number of $…

We give a complete description of all smooth projective complex varieties with $P_{2} (X) = 2$ and $q (X) = dim (X)$ .
